DREDGE BOAT CONSTRUCTION Filed May 2, 1932 q we Patented Sept. 6, 1932UNITED STATES WILLIE L. HOLBROOKS, OF HOUSTON, TEXAS c DREDGE BOAToonsrmrczrron Application filed May 2, 1932. Serial No. 608,833..

This invention relates to a dredge boat construction and has moreparticular relation to novel means for mounting the suction hoseemployed.

An object of the invention is to provide, in a dredge boat, a novel typeof hose box for mounting the suction hose, or suction pipe, employed.

As at present constructed the ordinary dredge boat has a. forwardlyextended ladder, hinged thereto, for supporting and controlling thecutters or diggers which disintegrate the shell or aggregate to berecovcred, and supported by said ladder there is a suction hose, orpipe, by means of which the material to be recovered is delivered to thebarge or other vehicle provided for the transportation of the same. Itis an object of this invention to provide, in a dredge boat,

novel means for anchoring said suction hose to the dredge in such mannerthat the hose. will be protected and at the same time will have therequired freedom, of movement.

With the above and other objects in view this invention has particularrelation to certain novel features of construction, arrangement of partsand use an example of which is given in this specification andillustrated in the accompanying drawing, wherein:

Figure 1 shows a fragmentary longitudinal sectional view of a dredgeboat illustrating the improvements.

Figure 2 shows a longitudinal sectional view of the hose box, showninstalled, and

b Figure 3 shows a front end view of said Referring now moreparticularly to the drawing wherein like numerals of reference designatethe same parts in each of the figures the numeral 1 designates thedredge boat as a whole, which may be of any selected construction.

Pivotally mounted on the bow of the boat 1 is the forwardly extendingladder 2 whose free end supports the cutting knives which dig up thematerial to be recovered. Be neath and supported by said ladder there isa suction pipe 3 through which the loose ma- 50 terial, dug up by saidknives, is conveyed,

by suction, and discharged onto a barge or other vehicle providedtherefor. 1 i

' Attached to the bow of the barge there is an inwardly, or 'aftwardly,extendedhose box 4 which is tapered, or gradually con- I6 tractedaftwardly and Whose rear end is open. This box i's'rectangular in crosssectional contour and its forward, or large, end

is fitted through the forward wall 5 of the dredge boat 1.Surrounding'the forward 00 end of 'saidbox and secured thereto onopposite sides of the wall 5 are the angle iron collars 6, '6' whoseoutstanding flan es are clamped. closely against said wall y the bolts 7which pass through said flanges and U wall and which secure the boxfirmly in place. .7 p

' The inner end of saidbox 4: has the end plate Ssecured thereto andhaving a central opening 9 and the adjoining ends of adjacent sectionsof the pipe 3 are clamped to opposite sides of said plate 8,. inalignment wlth saidropening 9, by theclam'pbolts 10. The suctionpipe 3extendsthrough said box 4 and the section thereof, extending into thebox, may be formed of flexible hose 11 so'that that portion of thesuction pipe, carried by the ladder, may swing freely with said ladder.The box 4 is of such dimensions that the pipe 3 may swing freely thereinas the ladder is swung vertically or laterally while carrying on thework and without injury to the dredge boat or to the suction pipe.

" The drawing and description disclose what is now considered to be apreferred formed of the invention by way of illustration only while thebroad principle of the invention will be defined by the appended claims.

What I claim is:

1. The combination with a dredge boat having a ladder pivoted theretoand a suction pipe which is supported by said ladder; an inwardlyextending box through, and at- 9 tached to, a wall of the boat throughwhich said pipe extends and to the inner end of which said pipe isattached.

2. The combination with a dredge boat having a ladder pivoted theretoand having said closing a suction pipe associated with said ladder;aninwardly extended box attached to the boat whose outer'end is open,said pipe extending through said box and anchored to, and'forming afluid tight joint with, the inner end of said box. 1

3. The combination with a dredge boat having aladder pivoted thereto andhaving a suction pipe associated with said ladder; an inwardly extendedbox attached to the boat whose outer end is open, said pipe extendingthrough said box and anchored to,

and forming a fluid tight joint with, the

inner end of said box, said pipe being formed flexible adjacentthe outerend of the box. 4. The combination 'with a dredge boat having a ladderpivoted thereto and a suction pipe which is supported by said ladder; aninwardly extending box through, and attached to, a wall of the boatthrough which said pipe extends and to the inner end. of which said p'peis attached, said box being flared outwardly. v 5. In a dredge boat, ahose box adapted to be attached to and to extend through a wall of theboat and whose outer end is open, means for closing the inner, end ofthe box,

suction pipe. v V

6. In a dredge boat, a hose box adapted to be attached to and to extendthrough a wall of the boat and whose outer end is op means for closingthe inner end ofthe box, said closing means forming'an anchor for asuction pipe, said box being outwardly flared.

In testimony whereof I have signed my name to this specification.
